It nudges him forward, pushing him across the shingle bank, dragging him to the edge of the flats; all the while, his sight is doggedly fixed on the point where he last saw the figure. In a shallow pool, he stands and surveys the vast expanse of muddy platforms.

Manning takes a few hesitant steps, but watches in quiet alarm as his boots sink deep into the swamp. A final step drops him several inches into the cloying mire; thick grey-green pools of water, rich with sediment, rush in to fill the grooves around his boots. He stops, heeding the signs, staring at the two pillars of wood that have brought him this far.’
